Specification of Letters Patent.

?atented Mar. 7, 1916.

Application filed April 20, 1914. Serial No. 833,287.

To all whom it may concern:

Be it known that I, JOHN R. DUNHAM, a citizen of the United States,resident of Berea, county of Cuyahoga, and State of Ohio, have inventeda new and useful Improvement in Lawn-Rollers, of which the following. isa specification, the principle of the invention being herein explainedand the best mode in which I have contemplated applying that principle,so as to distinguish it from other inventions.

My invention relates to lawn-rollers, its object being to provide alawn-roller which will be economical of construction and eificient inits operation and use.

Said invention consists of means hereinafter fully described andparticularly set forth in the claim.

The annexed drawing and the following description set forth in detailcertain means embodying my invention, the disclosed means, however,constituting but one of various mechanical forms in which the principleof the invention may be applied.

In said annexed drawing :Figure 1 represents a vertical section of alawn-roller embodying my invention. Fig. 2 represents a vertical, axial,fragmentary section, upon an enlarged scale, of that part of the rollerwhich embodies my invention. Fig. 3 rep resents a view similar to thatof Fig. 2 and showing a modified form of my invention.

The illustrated embodiment of my invention comprises a drum 1, havingend heads 2, 2, each provided with a central opening 3.

Referring first to the structure illustrated by Fig. 2, an axle tube 4extends through the openings 3 and outwardly beyond same a suflicientdistance to form journals for the roller bearings 5 of the handle 6, thetwo ends extending outwardly a suflicient distance to permit of theinterposition of a cupshaped washer 7 and an ordinary disk washer 8between the'head 2 to the adjacent handle-portion, as shown in Fig. '2.The washer 7 is made such that its inner surface will engage the head 2while the outside of the washer is out of contact with the joint madebetween the metal surrounding the opening 3 and the tube. This joint ispreferably made by welding in any suitable and approved manner.

The outwardly projecting ends of the axle tube are also made ofsuiiicient length to permit same to extend beyond the bearings andpermit the use of a cotter pin 9, passing through the outer end portion,and a washer 10 held in place thereby, said washer retaining the rollersof the bearing 5 laterally in place, as will be readily understood.

- In the modified form shown in Fig. 3, a solid bar 11 is substitutedfor the tubular axle 4:, the ends of the bar being made tubusary, inorder to effect a welded union, to

have the reduction of the mass of metal afforded by the tubular form ofthe bar at the place of juncture.

Having fully described my invention, what I claim and desire to secureby Letters Patent is In a lawn roller, the combination of a drumprovided with end heads each having a central opening; a tubular axlesecured in said openings and extending outwardly through same; a handlemounted upon said outwardly extending axle portions; anti-frictionbearings interposed between said handle and said axle portions, wherebythelatter form journals for said bearings; a spacing washer surroundingeach of said extending axle portions; a holding washer interposedintermediately of said spacing washer and handle; and a second and outerretaining washer suitably secured in place and adapted to hold saidanti-friction bearings in place on their journals. l9Signed by me, this16th day of April,

JOHN R. DUNHAM.
